Relive Thursday 18 August 2016 in Rio on olympic.org. The day was marked by the “triple double” of Usain Bolt, who won the 200m, the Brownlee brothers’ family double in the triathlon, Argentina’s first-ever hockey victory and the end of the beach volleyball, sailing and canoe/kayak sprint competitions

The star of the Rio 2016 canoe sprint competitions was unquestionably Hungary’s Danuta Kozák, the winner of golds in three of the four women’s competitions: K1, K2 and K4 500m. Elsewhere at the Lagoa Stadium, Germany’s Sebastian Brendel retained his C1 1,000m crown and won another in C2 over the same distance. Two other athletes to win back-to-back titles were New Zealand’s Lisa Carrington in the women’s K1 200m and Ukraine’s Yuriy Cheban in the men’s C1 200m.

Hungary's Danuta Kozak won her second gold medal of the Rio 2016 Olympic Games and retained her women’s kayak single (K1) 500m title at the Lagoa Stadium on 18 August.

Day 15 saw the curtain fall on the track and field action at London 2012, and once again it was Usain Bolt who stole the headlines on a day when 32 gold medals were won.

Great Britain's Ed McKeever stormed to gold in the men's Kayak Single (K1) 200m sprint at Eton Dorney, while Ukraine triumphed in the Canoe Single (C2) 200m.
